The songs are so collaborative that it is difficult to think of it that way. Robby wrote LMF but it's Ray's keyboard playing that makes the song magic. It's John's modified bossa nova beat in BOT that grabs you, etc, etc.

The Doors did it the fair way, which was an equal split, 25% each. The fiddling around that happens with some publishing splits is just silly - paying people line by line and so on. The Doors were an equal partnership, even though obviously Robby and Jim did the bulk of the lyric work the majority of the time, and Jim could come up with a melody line out of his head. Without Ray and John's musical input, the songs would not have been the successes they were, nor would they have carried the unmistakable Doors sound.
